So, one thing that was mentioned during the last TC meeting is to decide this in
a project basis. Don't open the door entirely but let projects sign up for this.
This will give us a more contained growth as far as projects with go-code go but
it does mean we'll have to do a technical analysis on every project willing to
sign up and it kinda goes against the principles of the big tent.

Exactly! This separation of domains is the reason why opening the door for JS
code was easier. The request was for browser apps that can't be written in

Just to stress this a bit more, I don't think the problem is the language per
se. There are certainly technical issues related to it (packaging, CI, etc) but
the main discussion is currently going around the impact this change will have
in the community and other areas. I'm sure we can figure the technical issues
